Patent

CA 2305193

The invention provides an alkoxylated aliphatic amine with 8-18 carbon atoms and 1-8 moles ethoxylation wherein the mole ratio of saturated to unsaturated aliphatic residues falls in the range 40:60 to 80:20. The invention also provides a cleaning composition which comprises: (a) 0.01-15 wt.% an alkoxylated aliphatic amine with 8-18 carbon ataoms and 1-8 moles ethoxylation wherein the mole ratio of saturated to unsaturated aliphatic residues falls in the range 40:60 to 80:20, and (b) 0.01-15 wt.% of an anionic surfactant. Cleaning compositions which comprise the amine show improved viscosity stability on storage. In the presence of the anionic surfactant at low pH the deposition of limescale on surfaces which have been treated with the composition is retarded.

Cette invention a trait à une amine aliphatique alcoxylée comportant de 8 à 18 atomes de carbone et dont entre 1 et 8 moles sont éthoxylées, le rapport molaire des restes aliphatiques saturés / insaturés tombant dans la gamme s'échelonnant entre 40/60 et 80/20. Elle concerne également une composition nettoyante comportant: (a), de 0,01 à 15 % en pourcentage pondéral d'une amine aliphatique alcoxylée comportant de 8 à 18 atomes de carbone et dont entre 1 et 8 moles sont éthoxylées, le rapport molaire des restes aliphatique saturés / insaturés tombant dans la gamme s'échelonnant entre 40/60 et 80/20 et, (b), de 0,01 à 15 % en pourcentage pondéral d'un tensioactif anionique. Ces compositions nettoyantes renfermant l'amine susmentionnée témoignent d'une stabilité de viscosité améliorée lors du stockage. En présence d'une tensioactif anionique à faible pH, le dépôt de tartre sur des surfaces traitées à l'aide de la composition se trouve retardé.
